It's not uncommon for there to be revisions, and they can be quite large. I think the concerning thing is that they're both large and negative revisions, although I'd say somewhat expected.
Overall though, I think these numbers are being reported truthfully as Trump has (maybe wants to) fire the head of the BLS - source
My suspicion is no one is able to accurately predict anything in the economy though due to Trump and Republicans going crazy with tariffs and killing the federal government.
I'm pretty sure the idea is two fold. First, being a politician wasn't supposed to be a full time job. The second is that politicians need to spend time in their home state to hear from constituents and be a part of their state (travel which used to take days/weeks for travel).
